The town of Remagen issued some very rare serienscheine pieces, which were originally from their verkehrsausgaben issues.
Only the pieces with overprints of 'Glocken-Bazar' are serienscheine. All the other similar pieces are verkehrsausgaben issues!
The first scan, below, are the serienscheine ones, which catalogue at 250 euros each.............followed by some variant verkehrsausgaben pieces. Very interesting notes to collect. (Pieces are all the same size in reality.....unlike some of my scans, unfortunately)
